Abstract
Quarter of a century has passed since the publication of Donald Norman’s “Design
of Everyday Things (DOET)” (The book was originally published in 1988 under the
title of “The Psychology of Everyday Things”). Now we have his newly revised and
expanded edition of DOET. In the 25 years since DOET was first published, technology
has extremely changed and many things have been developed, however, the situation
of people have almost remained the same which means that his essential principles or
rules for design are continue to be valid today. We describe what have changed and
what have not changed in the context of design of everyday things.
